Your leak is coming from the torque converter to front pump seal. The hotter the rubber gets, the softer it gets and eventually the fluid pressure pushes past.
Quote: To clarify things, BASICALLY: the torque convertor acts as a flywheel and ATF pump, no? Pumps it to the valve body which actuates hydraulic pistons to move the planetary gear system. This is what i have gathered so far so correct me if im wrong.
No, the torque converter is a fluid coupling, it connects the motor to the transmission through the input shaft. The outside of the torque converter is a mechanical coupling and drives the front pump which supplies hydraulic pressure to the trans systems.
At a minimum you should replace the front pump seal, the front pump bushing and the trans fluid and filter.
Your overheating may have been caused by a clogged radiator, which can transfer the heat of the truck itself, but cannot transfer the heat from the additional load of the trailered excavator. You can easily see a clogged radiator by draining the coolant till the top tank is empty, and looking for mineral deposits on / in the radiator tubes.
A second possibility is a defective fan clutch, but in my experience this will only cause overheating at low speeds (under 40 mph). At speeds higher than that the ram air effect flows enough air for cooling. I don't know if this applies since I don't know the tow speed.
